AUGUSTE CHARLES THEODORE BAUTAINE, ()F PARIS, FRANCE.

BRAKE FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 394,436, dated December 11, 1888.

Application filed October 27, 1887. Serial No. 253,558. (No model.)

To all whom, it may concern:

Be it known that LAUGUsTE CHARLES THEO- DORE BAUTAINE, a citizen of the French Republic, and a resident of Paris, France, have invented a certain new or Improved Brake System, ot' which the following is a specification.

This invention relates to a brake system, as set forth in the following specification and claims, and illustrated in the accompanying drawings, in which- Figure l is a perspective view ot' the pulley with grooves which is to be lixed to the hub of the wheel. Fig. 2 is a collar lined with some non-combustible material. Fig. 3 shows the collars placed on the pulley. Fig. 4 shows the brake system arranged to act on the wheel as well when the wheel moves forward as when it moves backward.

Similar letters indicate corresponding parts.

In the drawings, the letter A indicates a pulley keyed or fixed to the hub of the wheel. Into the grooves a c2 di a4 are placed collars B of suitable material-such as iron or steeland lined with some non-combustible material, b. Then the collars are in position, as seen in Fig. 3, a bolt, C, is passed through their upper rings, b b2 b3 b4, and a bolt, C', is passed through their lower rings, b5 b 57 bs. On the bolts C C swing the bows D D', perforated at d d for the reception of the ring or link E, Fig. 4. Two ropes, G G', are fastened to the link E and run in the grooves ai a of the pulleys A. A strap, H, strengthened by strips of steel or other metal, is secured to the bolt C, and another strap, H', is secured to the bolt C. These two straps are secured to a coupling, I, connected by a band, K, with the cross-bar of the brake-block L.

The brake-block L is made to bind or press upon the tire of the wheel. The free end of the rope G is secured to a lever or pedal placed near the driver, and the free end of the rope G is also secured to a lever similarly placed. These levers are not shown in the drawings. IVhen the wheel and pulley A turn in the direction of the arrow shown thereon in Fig. 4, the lever connecting with the rope G is actuated so as to pull on the rope, the ring or link E is drawn along with the rope, and a pull is exerted on the bow D and bolt C. The bolt C thus pulled causes the collars B to bind in the grooves d d2 d3 ([1. The pulley A, rotating in the direction ot' the arrow shown thereon in Fig. l, draws the collars B along' in the same direction, thus exerting a pull upon the bolt C', strap lI, and band K, and bringing the brake-block L against the tire or rim ot' the wheel, so as to retard or stop the rotation of the wheel.

\Vhe11 the wheel and pulley turn backward or in the direction opposed to that of the arrows shown in Fig. 4, the rope G is pulled instead of the rope G, and the collars li are again caused to bind in the grooves ofthe pulley, and the brake-block is drawn by the strap H against the wheel. The brake thus serves to stop the wheel, no matter in which direction the wheel turns. Said brake can thus be considered reversible, or adapted to act on the wheel,whether lthe wheel turns t'or` ward or backward.

In light vehicles the brake-block may be left out and the band K be lixed to thc body ofthe vehicle or other suitable point ot` attachment. In such case the stoppage is effected by the friction of the collars against the pulley A.

That I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with an annularlygrooved pulley, A, keyed to the hub ot' a wheel, of a series of double-acting circular brakebands, B, having separated ends, the bolts C C', respectively connecting the ends of said brake-bands, bows D D, connecting-link E, ropes G G', encircling the pulley and connected with the link, and straps H Il', connected with the bolts, substantially as and for the purpose described.

2. The combination, with a pulley, A, keyed to the hub ot' a wheel, of a series of doubleacling brake-bands, B, encircling the pulley and having separated ends, the bolts C C', passing, respectively, through said separated ends, and ropes G G encircling the pulley for drawing upon either of the connectingbolts at Will, substantially as described.

3. The combination, with a pulley, A, keyed to the hub of a Wheel, of double-acting brakebands B, encircling the pulley and having separated ends, the bolts C C, passing, re-

IOO

spectively, through the ends of the brakebands, straps H H', extending from the bolts and connected with a band, K, and ropes G G', encircling the pulley for drawing upon either of the connecting-bolts at will, substantially as described.

4:. The combination, With the annularlygrooved pulleyA, keyed to the hub of a Wheel, of brake-bands having separated ends, and each having its interior provided with a noncombustible lining, b, and the bolts C C', passing, respectively, through the ends of the band, substantially as described.
